Covers static strength, fatigue, and weld checks—all based on the latest crane safety design rules.

Fatigue History & Rainflow Counting

Use simplified or stress-history-based fatigue methods, including rainflow summation from your FEA results.

Weld Strength with Undermatching Logic

Automatically apply equations for weld material under-matching and effective weld length adjustments.

Realistic Fatigue Modeling

Factor in notch classes, slope factors, and reduced stress ranges for welded and non-welded joints.

Automated Stress Evaluation

Run nominal stress-based calculations with optional support for Hot Spot stress and directional weld logic.

Instant Reports

Generate traceable documentation with all safety factors, load groups, and fatigue life assumptions included.

About Standard

EN 13001-3-1+A2 (2018) defines structural safety requirements for crane components using the limit state method. It sets rules for static, fatigue, and weld strength evaluations of steel structures.

The standard is widely used across the crane and lifting equipment industry, ensuring compliance with EU safety regulations.

Key highlights include:

Nominal stress-based evaluation using elastic theory (no local stress concentrations)
Separate checks for static loads, fatigue damage, and weld strength
Fatigue groups and stress ranges defined by design life expectations
No allowance for overstress: verification is based on conservative safety principles

EN 13001 is part of the broader European standardization system and applies across all EU member states. It ensures design consistency, simplifies market entry, and supports safe lifting operations.

Frequently Asked Questions

Which version of EN 13001 is implemented in SDC Verifier?

We currently support EN 13001-3-1+A2 (2018) for crane steel structures.

What checks can I perform with EN 13001?

SDC Verifier supports static strength, fatigue strength, and weld strength checks based on the EN 13001 standard.

Can I use finite element results for EN 13001 fatigue analysis?

Yes. You can apply fatigue checks using FEA-derived nominal stress values and optionally include Rainflow Counting and Hot Spot Stress for advanced analysis.

Is the weld strength check based on yield or tensile values?

Both are supported. The calculation adapts based on whether weld material under-matching is applied, switching between yield and ultimate tensile strength logic.

Is the weld strength check based on yield or tensile values?

Both are supported. The calculation adapts based on whether weld material under-matching is applied, switching between yield and ultimate tensile strength logic.

Is the stress range reduced for compressive portions?

Yes. For non-welded or stress-relieved details, the effective stress range includes full tensile and 60% of the compressive portion, per EN 13001 guidance.
